Fruit scent and observer colour vision shape food-selection strategies in wild capuchin monkeys [PDF]

, 2019
The senses play critical roles in helping animals evaluate foods, including fruits that can change both in colour and scent during ripening to attract frugivores.

Individual importance of olfaction decreases with duration of smell loss.

Rhinology, 2020
BACKGROUND The personal importance of a lost neurologic - motor or sensory - function in several conditions has been shown to decrease as the afflicted patient becomes accustomed to not having that function.

An intrinsic association between olfactory identification and spatial memory in humans

Nature Communications, 2018
Olfaction, the sense of smell, may have originally evolved to aid navigation in space, but there is no direct evidence of a link between olfaction and navigation in humans.

Intrinsically Self-renewing Neuroprogenitors From the A/J Mouse Spiral Ganglion as Virtually Unlimited Source of Mature Auditory Neurons

Frontiers in Cellular Neuroscience, 2020
Nearly 460 million individuals are affected by sensorineural hearing loss (SNHL), one of the most common human sensory disorders. In mammals, hearing loss is permanent due to the lack of efficient regenerative capacity of the sensory epithelia and spiral

Prey aggregation is an effective olfactory predator avoidance strategy [PDF]

, 2014
Predator–prey interactions have a major effect on species abundance and diversity, and aggregation is a well-known anti-predator behaviour. For immobile prey, the effectiveness of aggregation depends on two conditions: (a) the inability of the predator ...

Olfaction and changes in body composition in a large cohort of older US adults.

The journals of gerontology. Series A, Biological sciences and medical sciences, 2020
BACKGROUND Poor sense of smell in older adults may lead to weight loss, which may further contribute to various adverse health outcomes. However, empirical prospective evidence is lacking.

Could humans recognize odor by phonon assisted tunneling? [PDF]

, 2006
Our sense of smell relies on sensitive, selective atomic-scale processes that are initiated when a scent molecule meets specific receptors in the nose. However, the physical mechanisms of detection are not clear.
